Got a question/issue to hopefully get an answer to. Disclaimer: You'll have to forgive me if I am missing the obvious as I and my son are completely new to this.

I had the understanding that this class (clone jr 1) for 2013 was running 4.50 on the front, 6.00 on the rear. For 2014 this has changed (?) to 4.50 on all four corners to align with WKA. Today I was told that WKA voted on the 8th and changed their specifications to run 4.50 front and 6.00 on the rear.

Again, totally new to this so no problem 4.5 on all corners or 4.5 front 6.0 rear..., just want to know before I buy tires for the season!

I'll be happy to address this guys. Wait a minute while I go put on my official BOD's hat....

The following is a little history of the wheel situation in the Junior 4-cycle classes. I can't claim credit for writing it, but I have the utmost confidence in it's validity.

So:
The way the 6" tire ended up being allowed in GSKA clone junior 1 is that when we originally started the clone classes we had:
Clone Junior 1: 7-10 years old - ran 4.50x5 front & rear
Clone Junior 2: 10-12 years old - ran 4.50 front and 6.00 rear
Clone Junior 3: 12-15 years old - ran 4.50 front and 6.00 rear

As a general rule, WKA has and all other asphalt sectioning bodies have 7-12 year old kids on 4.50 tires on front and rear. Rotax even has it that way on Minimax, which is 13 or 14 horsepower and a fairly hard tire.

GSKA had very low turnout in both junior 1 and junior 2 classes, so we combined the then Junior 1 and Junior 2 classes into one 7-12 class and allowed the 6.00 on the rear just so the Junior 2s that already had 6.00s can run them.

The bottom line is that the 7-12 class needs to be on 4.50 all around. The change is being made a month ahead of time and for the combining of the clone and pro gas classes to work correctly everyone needs to be on the same tire. Clone and Pro Gas in GSKA is NOT two separate classes. They are one 4 Cycle Sportsman class and the tire for 4 cycle sportsman is 4.50x5 front and rear.

Hope this answers any concern as to why this needed to be done, and while we ALWAYS try to avoid anything that increases cost, we feel the benefit to the class (and club), more than justifies it.

If anyone ever has any questions about anything we do, I feel I speak for the entire BOD when I encourage you to ask.

WKA combined all Sportsman 1 and 2 classes in the gold cup this year. The rule for sportsman 1 was 4.5's on front and rear last year. The sportsman pro gas last year was ran with the 6.0 option on the rear. This got over looked when the classes became combined this year. Since WKA printed the rule book there has been a trustee meeting allowing 6.0 as a option on the rear along with the 4.5 all the way around option. WKA should have this out on the pit board sometime this week.

Well I'm glad I haven't gone out and sunk a bunch of money into 6" rear tires yet! I did buy wheels that are currently not legal several months ago, though, before the 4.5" rule was posted. Sounds like the 6" may end up being okay but I guess I'll hold out on buying tires for the official word.
